wrt ear training, when I played regularly I could turn on the alternative rock station and pick up the chord progression for just about everything pretty quickly, and the melody and lead parts with enough fiddling around (I'd try for a couple hours at a time sometimes). I'm fairly confident that I could still pick up basic stuff (Green Day's latest, etc) within 10 minutes.

That's kind of the problem. I have this foundation, haven't played in forever, and have no idea where to go. Short of private lessons, I think learning theory inside and out may be my best step. I'd love to hear I'm wrong though, as well as more suggestions. Thanks to all.
